Implementation of the word game Wordle. Six guesses to find the target 5-letter word. After each guess the guesses so far are output, each letter color-coded green if it's in the word and in the correct spot; yellow if it's in the word but in the wrong spot; and no color if it's not in the word at all. The word to guess is chosen at random from a list of more than 2000 words.
Starting the system, and making guesses until the word is found on the fifth of six guesses. The output is omitted in the iex output here, but is seen in the screenshot below. Note that guesses are case-insensitive. (JEWEL was the word on April 1, 2025 (no fooling!)).
iex(1)> Dordle.start()
iex(2)> Dordle.guess "ARISE"
iex(3)> Dordle.guess "COVEN"
iex(4)> Dordle.guess "tubed"
iex(5)> Dordle.guess "wheel"
iex(6)> Dordle.guess "JEWEL"
This time failing to find the word after all six guesses (apparently the user couldn't give up on ARISE!).
iex(1)> Dordle.start()
iex(2)> Dordle.guess "ARISE"
iex(3)> Dordle.guess "COVEN"
iex(4)> Dordle.guess "tubed"
iex(5)> Dordle.guess "wheel"
iex(6)> Dordle.guess "ARISE"
iex(7)> Dordle.guess "ARISE"
It is also possible to provide your own starting word, perhaps with another person to do the guessing (and for my own testing). We see here how we can observe the internal state of the system as well.
iex(1)> Dordle.start("SLATE")
iex(2)> Dordle.guess "ARISE"
iex(3)> Dordle.guess "SHARE"
iex(4)> Dordle.guess "SPATE"
iex(5)> Dordle.get_state()
iex(6)> Dordle.guess "SLATE"
iex(7)> Dordle.get_state()
